Title: Combustion appliance and method for judging lifetime of the combustion appliance
Inventor: TAKESHITA NAOYUKI
IPC: F23N5/18
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To suitably inform a user of the time of replacing or repairing the component of a combustion appliance by judging the lifetime of the appliance according to the number of times exceeding the previously set abnormal value of a CO value measured while setting conditions of a combination of supply gas amount at the time of combustion and combustion continuing time are satisfied. SOLUTION: The value of CO generated by the combustion appliance 10 is measured by a CO sensor 48. The lifetime of the appliance is judged according to the number of times exceeding the abnormal value that the value of CO measured during the time when there is the combustion of satisfying the setting conditions of the combination of the supply gas amount at the time of the combustion and combustion continuing time. Normally, the rise of the CO concentration in the exhaust gas due to the abnormal combustion occurs due to the performance decrease of the appliance such as clogging by the deterioration of supply and exhaust system or heat exchanger, collapse or damage of supply and exhaust tubes or insufficient exhaust due to strong wind in the using environment.

Title: Display device for running amount of tape
Inventor: MATSUI TSUTOMU
IPC: G11B27/11
Filed: 1981-07-24
Abstract: PURPOSE:To calculate and display the running amount of a tape by detecting variations in the lamination amount of the tape on both sides of the center of the small window of a cassette half through a two-split photodetector and a differential amplifier, and then processing the detection output. CONSTITUTION:A reflector 28 is irradiated with a uniform light beam through the optical system in the figure. This beam 22 passes through the interval part between winding parts of a tape, and is collected to a two-split photodetector 31 through a cylindrical convex lens 30. The photodetection surface of the photodetector 31 is split into two parts right and left, and signals which correspond to the quantities of detected light at both the parts are inputted to a differential amplifier 33. Therefore, a detection output VD is the difference signal between the left and right signals of the two-split photodetector 31. The detection output VD is processed by a center position detecting circuit 34 to calculate an intermediate position M(t), an averaging circuit 35 remove the influence of the eccentricity of a hub to obtain a mean value M, and a tape-running-time arithmetic circuit 37 calculates a tape running time (t) from the M. At this time, tape thickness (d) is set and nonlinear correction is performed to display the running time and the running amount of the tape.
